From Conservapedia

He was the first composer to be honoured for instrumental compositions alone, which would be the most published and reprinted until Joseph Haydn’s music in the last half of the 18th century. Innovations in technique in both playing and composition would affect European chamber music into the 19th century. He is a significant figure in the development of the trio sonata and the concerto grosso.

His output was not large but is important. It consists basically of a series of sonatas (Op.1 to 5) the 6 concerti grossi, (Op.6) (published posthumously) and a small number of other works..
